COMPOSITION FUEL.

SPECIFICATION forming'part of Letters Patent No. 737,023, dated August 25, 1903.

Application filed October 22,1902.

To @ZZ whom it may concern:

Be it known that I, FREDERICK C. ROCK WELL, a citizen of the United States, residing at West Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Composition Fnel, of which the following is a specification.

This invention relates to a composition fuel which is manufactured of an inflammable vegetable body and metallic sulfates inti` mately united and formed into hard andcom'- pact pieces of suitable size.

The object of this invention is to provide a very simple, cheap, and convenient fuel which can be used economically in large or small quantities and which has such qualities that it will burn steadilyand emit bright smokelessflames having beautiful colors.`

The accompanying drawing illustrates one form in which the pieces of this fuel may be made.

It is preferred to make the body l of this fuel of peat or similar vegetable matter coked or carbonized. One manner of producing this body is to extract the superfluous moisture by pressure or otherwise from swamp or marsh 'peat and when dry by a suitable machine form and compact this peat into pieces of the desired shape and size. This shape is preferably eithera lozenge or cylinder; but of course it may be globular, or it may be a lump of any other regular orirregular. configuration. These pieces may be made in the sizes of the ordinary domestic fuel, and they preferably have indentations or recesses 2, as shown in the drawing. The

pieces of dried' and compressed peat may then be placed in a coking-kiln and'carbon- `ized in the usual manner. When coked and Seria] No. 128,2 86. (No specimens.)

pieces need not be immersed in such ar solution. The depressions or recesses maybe filled -with thelsulfate and chlorid. If desired, a small quantity of gas-tar may be mixed with' the peat for coking purposes, and the sulfate of copper, with the chlorid of sodium, may be mixed into the body before it is pressed into shape' and coked. These piecesfof fuel formed in this manner of these substances areinfiammable. They burn steadily and produce a bright hot fire, which'emits blazes :of

beautiful variegated colors, depending' upon the proportions of sulfate and chlorid Vin the i 6o composition. If sulfate of copper predominates, the flame will vary from green todark blue. freely, yet slowly, and leave comparatively little ash, and as the sulfate and chloridare thoroughly intermixed and intermingled with the body they last and produce attractive `flames until the fuel is entirely consumed.

I claim as my inventionl 1. A brightly-inflammable fuel composed of pieces of hardr porous, carbonized peatinn-v pregnated with metallicsulfate,substantially as specified.

2. A brightly-inflammable fuel composed of pieces of hard porous, carbonized peatiinpregnated with metallic sulfate and chloridof sodium, substantially as specified.

Fuel made in this manner will burn.
